CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 454,133, dated June 16,1891. Application filed March 14, 1891. Serial No. 385,024. (No model.)

To aZZ 1071,0772 it may concern:

Be it known that I, AMANDES HACKMAN, a citizen of the United States,residing at Peoria, in the county of Peoria and State of Illinois, haveinvented certain new and useful Improvements in Oar-Couplings, of whichthe following is a specification, reference being had to theaccompanying drawings, which is made a part hereof, and in which- Figure1 is a perspective View of the end of a car having the invention appliedthereto. Figs. 2, 3, and 4 are vertical longitudinal sections of adraw-bar head embodying the invention.

A represents the draw-bar; B, the draw-bar head; 0, the coupling-pin,and D the couplinglink.

The head B is provided with the customary end opening Z? for theadmission of the link and vertical opening I) for passage of the pin. Ithas also an interior cavity, in which is situated a lever E, pivotedupon a horizontal bolt F, which passes outward through elongated slots bin the sides of the head. Bearing against the rear side of this lever isa follower-block G, which fits in a suitable cavity in the draw-barhead, and is pressed against said lever by a spring H, fitting in asocket in the draw-bar, with sufficient force to hold said levernormally at the forward limit of its permitted movement, in whichposition it is shown in Fig. 2. YVhile in this position a projection e011 its front side, above the opening 1), lies across the opening Z), soas to hold the pin 0 in its elevated position. WVhile in this position,if the link isinserted through opening I) it comes against the frontside of lever E, and forces it back, compressing spring I-I until theprojection e is moved out of the path of the pin, whereupon said pinfalls, passin through the link, as shown in Fig. 3. If when in thislatter position the under end of the link is too low to enter theopening I) of the abutting draw-bar head of the next car and it bedesired to raise it, the lower end 6 of the lever E is moved inward orin the direction of the arrow in Fig. 2. In doing so the projection 6moves downward and depresses the inner end of the link D, with which itengages. This causes the outer end of the link to be elevated, sincesaid link rests at an intermediate portion upon the lower side of theoutward-flaring opening I).

The follower-block Ghas in its outer end a V-shaped groove, and theengaging face a of the lever E is of substantially complementary shape,except that the angle of the former is greater than the angle of thelatter. This construction holds the lever normally in the position shownin Fig. 2 or Fig. 3, and returns it automatically to such position afterthe removal of the power that has moved it to the position shown by Fig.4.

I is a shaft journaled to the endof the car and having two crank-arms,one of which '5 is connected by a chain or other suitable device withthe head of the pin D, and the other of which 1," is situated at theside of the car, so that the operator may reach it and withdraw the pinwithout entering between the cars.

.I is a shaft journaled to the under side of the car, and having acrank-arm j situated at the side of the car for operating it, and asecond crank-arm j, loosely connected to a rod K, having a loop 7c,through which the lower end 6 of the lever E projects, said loop beingheld in place on the lever by a pin K.

Having thus described my invention, the following is what I claim as newand desire to secure by Letters Patent:

1. The combination, with the d raw-bar head having openings b and bforthe admission of the link and pin, respectively, of a lever E, pivotedwithin the draw-head and having a projection efor engaging the inner endof the link and depressing it, and means for operating said lever,substantially as set forth.

2. The combination, with thedi'aw-bar head having openings 1) and h forthe admission of the link and pin, respectively, of the lever E, havingprojection e engaging the inner end of the link for depressing it, aspring for forcing said lever toward the outer end of the draw-head,a'pivot-pin F supporting it, and

means for operating it, said draw-head having horizontal slots h inwhich said pivot-pin rests and slides, substantially as set forth.

3. The combination, with the draw-bar head having openings Z), andb forthe admission of the link and pin, respectively, of the lever E, havingprojection e on its front side for engaging theinner end of the link,and having also the projection e 011 its rear side, the follower-blockG, having angular depression in which said projection e engages, aspring forcing said follower-block against said lever, a slidingpivot-pin supporting said lever, and means for operating it,substantially as set forth.

4. The combination, with the draw-bar head having openings b and b forthe admission of the link and pin, respectively, and having thehorizontal slots [2 or the lever E, having the projections and e on itsfront and rear sides,

respectively, the pivot pin F, occupying the slots b the follower-blockG, having the angular depression engaging the projection 0 the spring11', forcing said follower-block against said projection, the rod K,engaging the lower end 0 of said lever, and the crankshaft J, to whichsaid rod is connected, substantially as set forth.
